  Narcissus trevithian and Narcissus geranium: Analysis and synthesis of compounds

  摘要：

  The essential oils of two narcissus varieties, Narcissus trevithian and Narcissus geranium, obtained by extraction of flowers followed by high vacuum distillation of the absolute, were analyzed by GC/MS. After separation in fractions, unknown compounds were isolated by preparative GLC and their structures established by NMR/IR spectroscopy. The synthesis of a number of new compounds, found for the first time in narcissus oil, is described. The two narcissus species are compared with respect to their main components and odor quality. All compounds found so far in narcissus varieties are listed.

  Principal solvents, especially mono-ol and diol principal solvents, having a ClogP of from about 0.15 to about 0.64, preferably from about 0.25 to about 0.62, and more preferably from about 0.40 to about 0.60, are disclosed that have the ability to make clear aqueous fabric softener compositions containing relatively high concentrations of fabric softener actives having ester linkages in their long, hydrophobic chains. The fabric softener actives are either unsaturated, or have intermediate length chains (˜C 12-14 ) and the said principal solvents are used at levels of less than about 40%. Other solvents may be present. Some of the said principal solvents are novel compounds and/or novel mixtures. Premixes of the fabric softening actives, the principal solvents, and, optionally, other solvents are useful in the preparation of complete formulations by obviating/limiting the need for heating.
